Understanding Garage Door Springs

Before we dive into the how-to, it’s crucial to understand the role of garage door springs. These springs are responsible for counterbalancing the weight of your garage door, making it easier to open and close. There are two main types of garage door springs: torsion springs and extension springs. Torsion springs are mounted above the garage door opening, while extension springs are located along the sides of the door, above the horizontal tracks. This guide primarily focuses on torsion springs, as they are more common in modern garage door systems. Extension springs require a slightly different approach, and we strongly advise against attempting to adjust them yourself due to their inherent dangers.

Safety First

Working with garage door springs is inherently dangerous. These springs are under immense tension, and if they break or are improperly handled, they can cause serious injury. Before you even think about touching anything, remember these crucial safety precautions:

• Never work alone: Always have someone nearby who can assist you in case of an emergency.
• Wear safety glasses: Protect your eyes from flying debris.
• Disconnect the garage door opener: Unplug the opener to prevent accidental activation.
• Use the correct tools: You’ll need winding bars, a socket wrench, and possibly a ladder.
• If in doubt, call a professional: Seriously, it’s better to be safe than sorry.

Tools You’ll Need

Having the right tools is essential for a safe and successful spring tensioning. Here’s a list of what you’ll need:

• Winding bars: These are specifically designed for winding and unwinding garage door springs. Using anything else is extremely dangerous.
• Socket wrench: You’ll need this to loosen and tighten the set screws on the spring’s winding cone.
• Ladder: A sturdy ladder is necessary to reach the torsion springs.
• Gloves: Protect your hands from dirt and potential cuts.
• Marker or tape: To mark the current position of the spring.

Step-by-Step Guide to Tensioning a Torsion Spring

If you are not comfortable with any of these steps, please contact us at 801-418-9217 for professional assistance.

1. Secure the Garage Door: Manually close the garage door completely. Clamp the door to the tracks using C-clamps or locking pliers just above the rollers to prevent it from moving during the tensioning process.
2. Loosen the Set Screws: Locate the winding cone on the end of the torsion spring. Use your socket wrench to loosen the two set screws on the winding cone. Do not remove them completely.
3. Insert the Winding Bar: Insert one winding bar into one of the holes in the winding cone. Hold the bar firmly.
4. Unwind the Spring (If Necessary): If the spring is over-tensioned (door is hard to close), you may need to unwind it slightly. Carefully lift the winding bar to release tension. Insert the second winding bar into the next available hole in the winding cone to hold the spring in place. Remove the first winding bar and repeat the process until you’ve reached the desired tension.
5. Add Tension: This is the most crucial step. Insert one winding bar into a hole in the winding cone. Use the bar to wind the spring upwards, adding tension. The number of quarter turns needed depends on the door’s weight and height. A general rule of thumb is to add one quarter turn for every foot of door height. Mark the starting position of the spring with tape or a marker to help you keep track of the number of turns.
6. Secure the Set Screws: Once you’ve added the appropriate number of turns, hold the winding bar firmly in place. Tighten the set screws on the winding cone securely.
7. Remove the Winding Bars: Carefully remove the winding bars, one at a time, ensuring the set screws are holding the spring in place.
8. Test the Door: Remove the clamps from the garage door tracks. Manually lift the door halfway and then release it. The door should stay in place. If it rises or falls, you’ll need to adjust the spring tension accordingly.
9. Repeat on the Other Spring (If Applicable): If you have two torsion springs, repeat the process on the other spring, ensuring both springs have equal tension.
10. Reconnect the Garage Door Opener: Plug the garage door opener back in. Test the door’s operation with the opener to ensure it opens and closes smoothly.

Troubleshooting

Sometimes, even after following these steps, you might encounter issues. Here are a few common problems and potential solutions:

• Door is still heavy: You may need to add more tension to the springs.
• Door slams shut: You may have added too much tension to the springs.
• Door is uneven: The springs may not be equally tensioned.

If you’re experiencing any of these problems, it’s best to consult with a professional.

FAQs

Q: How often should I tension my garage door springs?

A: It depends on how frequently you use your garage door. Generally, it’s a good idea to inspect your springs annually and adjust the tension as needed.

A: While it’s possible, we strongly advise against it. Replacing garage door springs is a complex and dangerous task that should only be performed by trained professionals.

A: Common signs of broken garage door springs include a loud bang, a garage door that is difficult to lift, or a visible gap in the spring.
